No, not that one, the Watergate one. The man that outed himself as Watergate's "Deep Throat" just a few years ago has died. W. Mark Felt was a former FBI official that fed information to Bob Woodward at the Washington Post. I'm not going to get into great detail, but if you've read as much information about Watergate as I have, you would know that calling Felt "Deep Throat" as we understand it is a stretch. Woodward's telling of the story is very fictionalized and the real Deep Throat is actually an amalgam of many people. The idea of one key incognito source makes for good movie fodder, but it's far from reality.
